VIIBBATOR MECHANISM'.

Application filed June 28, 1926.

My invention relates to vibratory mechanism and has for its object theprovision of means whereby the contents of a receptacle may be suitablyagitated.

My invention is of particular advantage in connection with devices usedin the preparation of mixed drinks such, for instance, as are sold atsoda fountains. It is customary to place various ingredients, some ofwhich are in liquid form, into a receptacle and to thereafter agitatesaid contents so that these ingredients become thoroughly mixed and forma more or less homogeneous whole.

In my copending applications, Serial Nos.

107,513 and 107,514, I show devices of this general nature upon whichthe mechanism of my present invention is an improvement. In my copendingapplication Serial No. 119,049 filed of even date herewith, I claim theactuating mechanism for the vibratory element which is shown in thispresent application.

My present invention relates in general to agitating devices of thecharacter above described which use a rapidly oscillating ele ment,which oscillating element is. actuated by an electro-magnet suppliedwith intermittent current. In the preferred form of the device, thiselectro-magnet is supplied with 30 alternating current which may be ofthe customar frequency of sixty (60) cycles per secon so that theagitating element under the control of this electro-magnet makes onehundred and twenty (120) oscillations per tion I find serves the purposeof producing an adequate mixture of the ingredients such as thoseoutlined.

In my present invention I utilize in general the actuating mechanismshown in one or the other of my said copending applications, but I somount the agitating element that it is movable with respect to itssupport so that the receptacle or container may be moved into and out ofits position upon a suitable base without being lifted in the mannercustomary in devices of the prior art. My agitating element isswingingly mounted and as the container is removed from its place uponthe support it carries the agitating element with it and again restoresit to operative position when the container is again replaced.

I will describe one form which my invention may take more in detail byreferring second. This relatively high speed of agita- Serial No.119,050.

to the accompanying drawings in which Fig. 1 shows a device constructedin accordance with my invention, certain parts being broken away to moreclearly reveal features of construction;

Fig. 2 is a vertical sectional view of the agitator mounting means; and

Fig. 3 is a sectional view on line 33 of Fig. 2.

My improved device consists of a stand 10 having a base 11 which isadapted to support a suitable receptacle 12. A limit pin 13 is providedto hold the receptacle 12 in position, this limit pin being adjustableas for instance by having a plurality of openings such as the opening 14into which the pin 13 may be fitted. The devices controlled through theagency of the magnet 15 having a vibratory armature 16 to cause avertical reciprocatory motion of an agitating element 17 is allexplained in my said copending applications. The circuit through theelectroanagnet is controlled through the agency of two springs,respectively the springs 18 and 19 insulatingly mounted,

which springs are under the control of. a

plunger 20. This plunger in turn is con-- trolled by the receptacle 12and when the receptacle 1s in place, the circuit is closed as shown, butwhen the receptacle is removed, the spring action of the spring 18serves to free it from engagement with the spring 19. The armature 16controls a vertically movable reciprocatory element 21 which motion istransferred to the agitator 17 as will be clear.

My invention concerns itself with the provision of suitable mechanismsuch as embodied in connection with the element 22 presently to beexplained whereby the agitator rod 28 may be swung from the posi- 2 tionshown in full lines in Fig. 1 to the position shown in dotted lines inFig. 1. By reason of this construction the receptacle 12 can be veryeasily removed from its place upon the base 11. It need merely be liftedto clear the position of the pin 3 and can then be withdrawn. As it istaken away fronrits support it engages the agitator rod 23 and swings itinto its dotted line position so that the receptacle can then veryeasily be disengaged from the agitator rod. When the receptacle isfilled with unmixed ingredients to be again subjected to the actuationsof the device,then the receptacle is moved back into the position shownin liig. 1 having first engaged the agitator 17 and swung it partiallyinto its vertical position, suitable means which are provided inconnection with the element serving by snap action to swing the agitatorrod 23 the remaining distance so that it again assumes its verticalposition.

I will now describe more in detail one form of mechanism which can bringabout this result. The element 22 is preferably of circular form havinga slot 2% cutacross its lower extremity. This slot is sufficient toloosely accommodate the fiat head 25 formed at the upper extremity ofthe otherwise circular agitator carrying rod 23. There is also providedacross this slot 2 1. a cross piece 26 which is fiat, but has upper andlower rounded surfaces as more clearly apparent from Fig. 2. This crosspiece is designed to hold the head in position but to at times permitthe entire removal of the rod 23 from connection with the device 22.This removal or the rod 23 together with its agitator is very desirableand forms one of the advantageous features of my invention. The agitator17 is utilized for agitating various ditferent kinds of ingredients in areceptacle and it is desirable to at times clean this agitator, not onlyto prevent the mixture of undesirable ingredients into a pre determineddrink, but for sanitary reasons so that this agitator and rod may bekept in a sanitary condition such as is necessary and highly desirable.

The head 25 when introduced in place as shown in Figs. 2 and 3, isproperly held in position by the cross piece 26 but it may be rotated toa distance of 30 or more without interfering with its support upon saidcross piece. Should the rod 23 be rotated to a greater distance, say 90,then the slot 27 provided in said head permits the entire removal of therod by sliding it downwardly as the slot 27 will then be aligned toclear the cross piece 26. The head 25 is provided with two notches,respectively the notch 28 and the notch 29. These notches are designedto cooperate with a spring pressed plunger 30 so that the rod 23 iseither held in the vertical position shown in Fig. 1, or its angularposition shown in the same illustration. That is, the notch 28corresponds to the vertical position of the rod 28 and the notch 29corresponds to the dotted position of this rod 28 in Fig. 1,. Theplunger 30 is mounted in a hole 31 provided through the element 22 andis held in position by means of the compression spring 32. Thiscompression spring normally tends to push this head 30 downwardly.Suitable backing for the spring is provided by the screw threaded rod 21which has screwthreaded engagement with the screwthread provided in thehole 81 and this rod 21 in turn is suitably supported by thesprings 33and 34, the spring 23-1 carrying the armature 16. The rod 21 is screwedinto position suiiiciently to give therequired compression to the spring32. The notch 28 is of such a character that it the rod 23 is partiallymoved toward its vertical position by the container 12 when in position,that the inclination of this notch in connection with the spring pressedhead 30 is su'lticient to complete the movement of the rod 23 into itsvertical position. \Vhen the rod is in its inclined position, the head30 serves to hold it in that position by virtue of its engagement withthe notch 29.

From what has thus been described, the nature of my invention will bereadily clear to those skilled in the art and it will also be seen thatmodifications may be made without departing from the spirit thereof.
